STANCHION-FASTENER AND SHOCK-ABSORBER.

Specification of Letters Patent.

Patented Aug. 2st, 1920.

Application filed May 28, 1917. Serial No. 171,460.

To all whom it may concern:

Be it known that I, Crmnnns M. STEVEN- soN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in stanchion- Fasteners and Shock-Absorbers, of which the following is a description.

My invention belongs to that general class of devices known as stanchion fasteners, and relates particularly to a device for securing or anchoring the lower end of a stanchion in such manner that the same is securely anchored, and yet yielding to the desired extent. The invention has among its objects the production of a device of the kind described that is simple, eflicient, convenient, durable, compact and satisfactory. It has among its further objects the production of a device of the kind that may be adjusted to secure the desired alinement, which closely fits the curb, and is noiseless and easily installed. It has particularly as an object the production of a yielding retainer for .the stanchion which will prevent any shock when a cow retained by the stanchion surges forward or backward in rising or lying down, or at other times. Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a view in elevation of a stanchion equipped with my device;

Fig. 2 is a sectional view taken substantially on line 22 of Fig. 1;

Fig. 8 isa sectional view taken substantially on line 3-3 of Fig. '2;

Fig. 4 is a top plan of a modified bar, and

Fig. 5 is a top plan of a portion of another modified bar.

Referring to the drawings, in which the preferred forms of the device are shown, 1 represents any suitable or desired style of stall head or frame construction, which is ordinarily mounted in a curb 2 and carries the stanchion 3. The lower ends of the stanchion members may be secured in any desired manner, that illustrated being a double acting stanchion, and the lower ends of the parts are pivotally secured to a part 4. it may be mentioned that part 4c represents either a separate part as shown or a part carried by or forming a part of one of the lower ends of the stanchion, this being immaterial in so far as the present invention is concerned.

Arranged at the lower end of the stanchion is a bar 5 of suitable material, size and shape, that shown being waved or corrugated between the ends with a straight central portion 6, to which a bracket or part 7 may be secured. In the construction shown the bracket 7 is secured in place by bolts or screws 8. A reinforcing plate 9 may be arranged as shown, if desired, but the same is not necessary. The part 4 is provided with a depending stem or stud 10 arranged to extend through and be engaged by the bracket 7. The lower or free end of the same may, if desired, be offset. or headed so as to pre: vent the withdrawal of the part from the bracket. It may be mentioned that the stud or depending part 10, carried by'the part 4 or stanchion parts may be cast or otherwise formed. While any equivalent construction will serve the purpose, that shown is exceedingly simple, and has been found very desirable in practice.

The shock-absorbing part 5 may be secured or anchored in any desired manner. As shown, the ends of the same are preferably secured to the stall frame by brackets 12. In this case I prefer to twist or turn the ends 11 of the bar 5, so that they lie substantially as shown in the drawing. The brackets 12 may be of any desired construction. In the construction illustrated the same are formed with a flange portion 14, provided withthe desired number of openings or slots 15 therethrough, disposed as desired, the brackets being secured in place on the stall frame by the bolts 18 connecting the flanges 17 clamping the device in place. It will be noted that the brackets 12 are formed with lugsor bosses 13 arranged to pass through the slots in the ends of the bar. In this connection I prefer to form the opening 22 through the ends 11 of the bar slightly elongated to allow a slight play, but it is immaterial whether the elongated opening is made in the end 11 of the bar or in the bracket flange 14:-

The oonstruction shown in 4 is similar except that the bar 20 is made straight,

the ends 21 being turned as previously described for the other construction, and formed with the openings 22. In the con.- struction shown in Fig. 5, the bar is in two parts 23-23, which may be overlapped.

he holes may be in the form of slots, so that the length of the spring or bar may be varied to fit various size stalls, 6., wide or narrow or intermediate sizes, and the part 14 secured at the center.

One of the many advantages of this construction is that the stall and frame may be set up and shipped by the manufacturer with the stanchion mounted in place, so that it is only necessary to set up and secure the stall as desired. It will be noted that all noise or rattling, as in the'case of chains or like fasteners, is entirely eliminated. The same may be set as close to the curb as desired, and it is not necessary to directly fasten'the same to the curb, which is often inconvenient, and perhaps expensive, where a cement curb is employed. The device may be adjusted forward or backward, or that is alined as desired. The same is particularly comfortable for the cattle, inasmuch as the stanchion, while firmly held or anchored at the bottom, is yieldable and will give or spring at all times when the cow surges forward or backward, as previously mentioned. lVherethe same is set substantially close to the curb, as it may be, the same also has a tendency to prevent the feed from falling over the curb on to the stall floor. The same is applicablefor practically any type of stall construction, and any type of stanchion, regardless of whether the same is single or double acting, or how the same is carried at the top. It. has been found in practice that a portion of the weight 011 the stanchion being carried by the device, the same will work easier 'at the top and not tend to bind and work hard.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

' What I claim as new and desire to secure by Letters Patent is 2 p 1. The combination of a pair of spaced supports, and a stanchion, of attaching means including a resilient bar having its supports, and a stanchion, of attaching means including a resilient bar, pivotal sliding connections between the end portions of said bar and said supports, and means for connecting the stanchion to the resilient bar intermediate the ends thereof.

3. The combination with a stall frame, and a stanchion having its upper end operatively connected with the frame, of attaclr ing means including a bar extending horizontally across the lower end of the stall frame and having its end portions connected with opposite side bars of the frame, said bar having a resilient portion intermediate its ends, and means connecting the lower end of the stanchion with said bar intermediate the ends thereof. 7

4. The combination of a pair of spaced supports, and a stanchion provided with a projecting stud at one end, of attaching means including a bar having its end portions connected with said supports, said bar having a resilient portion intermediate its ends adapted to yield laterally, a plate secured to the bar intermediate the ends thereof, said plate having an opening extending therethrough, the stud on the stanchion fitting into the said opening. 7

5. The combination of a pair of spaced supports, and a stanchion, of an attaching means including a resilient horizontally extending bar of general oblong shape in cross section, the bar being disposed with its broad side extending in a vertical plane and having end portions twisted a quarter of a turn, said end portions being connected with said supports, and means for connecting the stanchion to the resilient bar intermediate the ends thereof.

6. The combination of a pair of spaced supports, studs on the supports, and a stanchion, of attaching means including a resilient bar having slotted end portions loosely engaging the studs on the supports, and means for connecting the stanchion to said bar intermediate the ends thereof.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses. 7
